Gemstone Necklaces


The most valuable gemstones are highly-priced due to their rarity. They also emit blinding lusters and comparatively tougher hardness. Four of the most precious and considered as the most valuable gemstones are ruby, sapphire, emerald, and diamond. 


These gemstones are also valuable but are relatively more abundant in nature than the precious gemstones. However, some of these precious gemstones also exhibit remarkable eye-catching properties that can make them equally valuable as precious metals. Some are even in high demand, which further increases their prices. 


These are inorganically formed crystals that are characterized by their chemical composition, luster, color, hardness, streak, and other physical properties that distinguish them from other crystals. Fresh crystals are cut, polished, or processed to form gemstones or be sold for other economic purposes. Some gemstones that originated from such crystals are sapphires, diamonds, quartz varieties, etc.


Organically formed crystals are sourced from biologically produced crystals. They can be remnants from fossilized living creatures or a substance produced by a living organism. Examples of these gemstones include pearls, amber, corals, etc. 


These are aggregates of minerals or with some undifferentiated matter that forms one solid material. They can also be cut and sold as faceted, calibrated gems, or cabochons that can also be valuable jewelry. Examples of these include obsidian, bloodstone, marble, etc.

Buyer’s Guide: Features to Look Out for Before Buying the Best Gemstone Necklace

Choose the Right Gemstone Type

With the different types of gemstones described above, you can assess what type would suit your style and your budget. Some gemstones are rarer than most types, making them more valuable. However, some gemstones are also valued for their brilliance, hardness, and rich colors.

Suitable Gemstone Size

Gemstones are usually measured in millimeters through their diameter. They range from 6-11mm cuts to be conveniently strung into a necklace. The larger its size is, the more costly it would be, but it will also be more eye-catching, best used for formal events.

Necklace Length

You need to match the necklace length with the width of your neck and how you’d like your necklace to appear, hanging from your neck. Usually, gemstone necklaces that measure 16in at most would most likely appear as chokers or leave minimal space, while 18in necklace lengths or more would drape down with enough space for your neck.

Durable Material

Ensure that your gemstones are protected with rims or plating, especially if they are soft and authentic. They could accidentally bump on hard surfaces when you’re not aware, particularly if they are organic such as pearls, making them susceptible to wear and becoming uneven. 

For the metal clasps or other metal strings or chains attached to your gemstone necklace, especially for pendants, ensure that they have a high-quality metal material to match the elegance of your gemstones. Most reputable gemstone necklaces would use white or yellow gold metal clasps or chains with some protective plating to make them resistant to tarnishing.

Secure Metal Clasp

Most necklaces can have flimsy clasps that can be severed easily, or some even complain of very complicated or hard to open clasps that would be an inconvenience if you were to remove it alone. You can discover other gemstone necklaces that provide a secure clasp that would have an uncomplicated opening and locking mechanism that wouldn’t compromise the security of your gemstones hanging on your neck. 

You can also buy the gemstone or a pendant and provide a customized chain for your necklace. This way, it would be more personalized and would assure you of the durability of the chains. However, this would add an extra cost, which may be impractical in some cases, especially if the necklace itself is expensive already. 

Verified Authenticity

It would be best to get gemstones from verified vendors or sellers specializing in jewelry for those who plan to buy authentic gemstone necklaces. Reputable brands and sellers would even include a Certificate of Authenticity with your necklace purchase to guarantee your gemstone’s legitimacy.

Good Reviews and Ratings

If were to be meticulous in choosing your products before buying them, you will read some reviews from verified purchasers who’ve already seen the product personally. With that, you can assess what features are great and what makes that gemstone necklace worth your money. You would know that it’s a buy if it has been garnering many good reviews with soaring ratings. 

Within Your Budget

When you compare various products in the market, you can assess what features set them apart from the other products. If you saw one gemstone necklace that is just as great as the other necklace types sold at a higher price, then you must pick it over the others for a good deal. 

You can sacrifice some negotiable features for your gemstone necklace if you don’t have enough budget to buy the most extravagant ones in the market today. You can start by choosing the type of gemstone necklaces that would fit your budget, then ensure that you get the authenticity and wear-resistance and be happy with how it looks overall. 

It would be best to invest in your gemstone necklace’s longevity and design so you can be satisfied with your purchase while making it cost-effective in the long run. It would be a plus if the sellers have satisfaction guarantees, money back, and other warranties that would be useful throughout your necklace’s life.

FAQs – Frequently Asked Questions

How do I know if my gemstones are authentic?

First, when buying gemstones, you must consider how trustworthy or reputable a seller you plan to buy on. Some are authorized by well-known organizations or are regulated by expert jewelers. They would send you a certificate of authenticity along with your purchase. 

However, you may already have a questionable gemstone in possession, not knowing its genuineness. In that case, you can bring it to an expert jeweler to ensure your gemstone’s safety and expect credible results. Some people test their gemstones using invasive materials or chemicals to dissolve your gemstone, making it less pretty and valuable afterward.

Is it safe to buy gemstones online?

It would be perfectly fine if you pick a trustworthy and credible seller that has been running for a considerable number of years already. You must examine their website and ensure that they have great customer service with already verified purchasers that reviewed most of their sold items. Reputable sellers would also offer flexible return policies and other warranties to guarantee your purchase satisfaction. 

The Blue Nile and James Allen are some of the most trusted sellers for precious gemstones. Amazon is a more open market and should still be observed through reviews and ratings to find more detailed descriptions about their sold product.

How can you effectively test synthetic diamonds from genuine ones?

You must remember that lab-created or synthetic diamonds can also be classified as genuine diamonds and are valuable as well as they are made with the same structure as natural diamonds. However, naturally occurring diamonds can be distinguished from synthetic ones through a couple of tests that makes them extremely valuable. 

Thermal conductivity tests work for differentiating diamond simulants such as cubic zirconia from the naturally occurring diamond. However, a new diamond simulant called moissanite can only be differentiated using electrical conductivity tests. A naturally occurring diamond also has the hardest bonding pattern making it the hardest mineral in the Mohs Scale of hardness. Only a natural diamond can scratch another natural diamond.
